A sustainable competitive advantage occurs when an organization acquires or develops an attribute or combination of attributes that allows it to outperform its competitors. These attributes can include access to natural resources or access to highly trained and skilled personnel human resources. It is an advantage (over the competition), and must have some life; the competition must not be able to do it right away, or it is not sustainable. It is an advantage that is not easily copied and, thus, can be maintained over a long period of time. Competitive advantage is a key determinant of superior performance, and ensures survival and prominent placing in the market. Superior performance is the ultimate, desired goal of a firm; competitive advantage becomes the foundation. It gives firms the ability to stay ahead of present or potential competition and ensure market leadership.
